C-Tzu Universal 5/6-Hole Short Hub Adapter 5in Depth Black Billet Aluminum for GM/Chevy/Pontiac Trucks

The C-Tzu Universal 5/6 Hole Short Hub Adapter is a billet-aluminum, short-depth steering wheel spacer that converts common 5/6-bolt wheels to fit many GM, Pontiac and Chevy truck tilt columns quickly and securely.

This short hub adapter is engineered to bridge aftermarket steering wheels and older American car and truck columns without extensive modification. Finished in black powder coat over polished billet aluminum, it resists corrosion and heat while providing a precise, low-profile fit. The adapter is intended for classic and late-model vehicles listed in the fitment notes and for users who want a compact, reliable connection between wheel and column.

Which vehicles will this C-Tzu adapter fit?

This adapter covers a wide range of American vehicles, particularly trucks and pickups from Chevrolet, GMC and Pontiac plus many American Motors models within the stated years. It fits standard 5/6-bolt steering wheels and is compatible with most tilt columns, but not extension-bar type columns or airbag-equipped wheels.

• Fits many 1970–1988 American Motors (excluding Alliance/Encore)
• Compatible with 1969–1995 Chevrolet and GMC trucks
• Works with Pontiac pickups and Cherokee models listed in fitment
• Not suitable for steering wheels with airbags or extension-bar columns

How does the short 5-inch depth affect installation and steering feel?

The adapter’s 5-inch depth (from spline end to top) provides a compact, low-profile mounting position that keeps the wheel closer to the column for a factory-like reach. That reduced offset helps preserve original ergonomics and avoids excessive wheel extension, which can otherwise alter leverage or sightlines.

• 5-inch depth for a compact, factory-style wheel position
• Shorter offset limits changes to steering geometry and feel
• Direct-screw fit avoids lengthy modifications or adapters

What materials and machining quality should I expect from this C-Tzu hub?

The adapter is CNC-machined from billet aluminum, then polished and treated with a black powder coat for durability. The combination of hardened aluminum and precise hole tapping resists wear, reduces corrosion risk, and ensures bolt holes align cleanly for repeatable installs.

• Billet aluminum body for strength with reduced weight
• Fine polishing plus black powder coat for corrosion resistance
• Accurately drilled and threaded holes for smooth bolt engagement

How simple is the install process and what tools are needed?

Installation is designed to be straightforward: the adapter screws onto the column spline and the wheel mounts with standard 5/6-bolt patterns. No cutting or welding is required, but basic hand tools and correct torque on fasteners are necessary to secure the hub and wheel safely.

• Screws onto column spline; compatible with most 5/6-bolt wheels
• No vehicle modification required for compatible columns
• Requires standard socket set, torque wrench, and thread-safe hardware

Who this is for: The C-Tzu Universal 5/6 Hole Short Hub Adapter is aimed at classic car restorers, custom truck owners, and anyone swapping aftermarket wheels onto older GM, Chevy, GMC or Pontiac tilt columns. It’s best for projects where a compact, durable, and clean-looking connection is needed without reworking the column — not for vehicles equipped with factory airbags or nonstandard extension columns.
